晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

IMPORTANT:
This sample was originally intended as an exercise for the ICU Workshop (September 2000).
The code currently provided in the solution file is the answer to the exercises, each step can still be found in the 'answers' subdirectory.

Day 2: September 12th 2000
Pre-requisites:
1. All the hardware and software requirements from Day 1.
2. Attended or fully understand Day 1 material.
3. Read through the ICU user's guide at

#Date/Time/Number Formatting Support
9:30am - 10:30am
Alan Liu
Topics:
1. What is the date/time support in ICU?
2. What is the timezone support in ICU?
3. What kind of formatting and parsing support is available in ICU, i.e.
NumberFormat, DateFormat, MessageFormat?
INSTRUCTIONS
------------
This exercise was first developed and tested on ICU release 1.6.0, Win32,
Microsoft Visual C++ 6.0. It should work on other ICU releases and
other platforms as well.
MSVC:
Open the file "msgfmt.sln" in Microsoft Visual C++.
Unix:
- Build and install ICU with a prefix, for example '--prefix=/home/srl/ICU'
- Set the variable ICU_PREFIX=/home/srl/ICU and use GNU make in
this directory.
- You may use 'make check' to invoke this sample.
PROBLEMS
--------
Problem 0:
Set up the program, build it, and run it. To start with, the
program prints out the word "Message".
Problem 1: Basic Message Formatting (Easy)
Use a MessageFormat to create a message that prints out "Received
<n> argument(s) on <d>.", where n is the number of command line
arguments (use argc-1), and d is the date (use Calendar::getNow()).
HINT: Your message pattern should have a "number" element and a
"date" element, and you will need to use Formattable.
Problem 2: ChoiceFormat (Medium)
We can do better than "argument(s)". Instead, we can display more
idiomatic strings, such as "no arguments", "one argument", "two
arguments", and for higher values, we can use a number format.
This kind of value-based switching is done using a ChoiceFormat.
However, you seldom needs to create a ChoiceFormat by itself.
Instead, most of the time you will supply the ChoiceFormat pattern
within a MessageFormat pattern.
Use a ChoiceFormat pattern within the MessageFormat pattern, instead
of the "number" element, to display more idiomatic strings.
EXTRA: Embed a number element within the choice element to handle
values greater than two.
ANSWERS
-------
The exercise includes answers. These are in the "answers" directory,
and are numbered 1, 2, etc.
If you get stuck and you want to move to the next step, copy the
answers file into the main directory in order to proceed. E.g.,
"main_1.cpp" contains the original "main.cpp" file. "main_2.cpp"
contains the "main.cpp" file after problem 1. Etc.
Have fun!
